yea goff, high quality synthetic oil like ELF feels damn great! I felt it when changing from Shell to Hi-rev as well. The engine is quieter too.
dude_pare01, u go around phil? 12 hour engine run is crazy
arechin, yea, 20W-50 should be fine if u travel damn long distance, because ur ur engine is always running at 100C for a long period. All engine oil regardless of rating and type (mineral, semi or full) has exactly the same viscosity at 100C. Short distance folks should use better rating such as 10W-40 because it reduces wear and tear when engine is cold.
What I meant is, when engine is cold , 10W-40 oil is thinner than 20W-50. However, when 20W-50 and 10W-40 reaches 100C, both of them will have the same rating, 0W-0. All engine oil are designed to operate 0W-0 at 100C. 20W-50 or 10W-40 is just the rating at certain temperature, maybe 0C (not sure abt tis thou).
